In the mean time:

I'm posting it just for the record as I believe anyone interested is up-to-date.
Can't wait for version 12 to hit the chrome-dev channel ;)
BTW - is there a simple, built-in way to check which protocol version is implemented in the browser I'm using (chrome 11.0.686.1)?

Working on a Mojolicious site that supports ietf-07 (hybi-07?) but chrome doesn't appear to co-operate - The server registers the websocket connection but chrome never completes the connection it seems.
I'm using "13.0.781.0 (Developer Build 87259 Linux)" which I downloaded today - there are no warnings or errors which make this any easier to diagnose.
Knowing what version of the protocol Chrome supports (and getting a console error/warning) would be extremely useful
